Hi there guys, I am thinking about swapping my app (MapitGIS) to locationtech library, one of my users would like to use projection 3375, however I am running into similar problem as described here:

https://gis.stackexchange.com/questions/261723/proj4js-gives-wrong-result-for-epsg3375

for: 3.06268465621428, 101.70979078430528 (lat,lon)

I am getting 744626.6428051005, -103618.62269607143 result.

Expected: 412597.532715, 338944.957259

Any idea?

Kind Regards, Andrzej
